Add CAM support to xmcd. This patch makes xmcd autodetect a CAM system,

and use the appropriate SCSI interface code.

This patch has been sitting around for 3 weeks, and no one committed it, so
I thought I'd commit it before the ports freeze tomorrow.

xmcd-2.3pl1 will have native CAM support, but since it looks unlikely it'll
be out before tomorrow, we'll have to go with the "unofficial" CAM patch.

PR:		ports/7957
